Code to Help me learn on how to GO and on how to blockchain

Read blog post to see a walkthrough of the code.

Deployment steps:

• Add ENVS to the example file .env
• go run main.go
• open a web browser and visit http://localhost:8080/
• to write new blocks, send a POST request (curl -X POST -H "Content-Type: application/json" -d '{"BPM": 50}' http://127.0.0.1:8080) to http://localhost:8080/ with a JSON payload with BPM as the key and an integer as the value. For example:

{"BPM":50}

• Send as many requests as you like and refresh your browser to see your blocks grow! Use your actual heart rate (Beats Per Minute) to track it over time.
